How to view data being sent to a port?

[ken]

Hi all,
I'm using the MS VB example "How to: Receive Strings From Serial Ports
in Visual Basic" and would like to see the data being received. I have
two virtual serial ports COM5 and COM6 setup using Virtual Serial
Ports Driver XP . The code below is looking at COM6 and I'm sending
data via COM5 with Hyper Terminal.

I know this works because when I send data (MS VB example " How to:
Send Strings to Serial Ports in Visual Basic") on COM6 I'm able to
view it on COM5 with Hyper Terminal.

Can anyone tell me how to view the data being received? I tried doing
things like cboReceive.text = Incoming, cboReceive.text = returnStr .
So any help would be great. Thanks all.
Regards,
Ken

Function ReceiveSerialData() As String
' Receive strings from a serial port.
Dim returnStr As String = ""

Using com1 As IO.Ports.SerialPort = _
My.Computer.Ports.OpenSerialPort("COM1")
Do
Dim Incoming As String = com1.ReadLine()
If Incoming Is Nothing Then
Exit Do
Else
returnStr &= Incoming & vbCrLf
End If
Loop
End Using

Return returnStr
End Function
